LG Refrigerator Making a Humming Noise – Quick Fix

If you find that your LG refrigerator is making a humming noise, it is nothing to worry about. As long as the volume of the noise is low and comfortable, the refrigerator is operating normally.

Typically, a refrigerator compressor makes a low humming noise during normal operation. This is an indication that the refrigerator is working as it should.

However, if the noise becomes excessively loud that you can hear it from another part of the house, it means the compressor has developed a fault.

The loud sound may be pointing to the fact that the refrigerator’s compressor is straining too hard to keep the refrigerator cool. If this is the case, one or more components have failed.

What to Check…

Heat overload can cause the compressor to work that hard. Therefore, find the origin of the excess heat and plug it.

Check the condenser coils for dirt and clean them if necessary. The same applies to the compressor. But before doing this, disconnect the refrigerator from power.

Also, check the door gasket and ventilation around the refrigerator. A weak gasket lets warm air in too easily and poor ventilation heats up the compressor and coils.

LG Refrigerator Humming Noise Stops When Door Open – Solved

A buildup of frost on or around the freezer fan can cause this noise. Typically, the fan motor stops running once you open the door of the freezer or refrigerator. So if the humming noise stops when you open the door, check the evaporator fan.

Open the rear panel inside the freezer and inspect the fan. If there is ice around it, thaw the fan with a dryer or steamer. You can also run a defrost cycle if the refrigerator has an automatic system. Otherwise, run a manual defrost.

Once done, find out why there is an accumulation of ice around the fan. There may be an opening through which warm air enters the unit. Hire a certified technician to diagnose and fix the problem.

Important Note

Always disconnect the refrigerator or freezer from electric power before performing any diagnostic or repair work. Leaving the refrigerator plugged in is dangerous.
